Abstract
An induction generator is connected to a three-phase mains. The induction generator includes a control unit () connected to a current transformer (), on one (L) of the lines (L, L, L) of the three-phase mains. The induction generator includes a number of power sections (). Each power section () supplies one of the induction coils (). A control unit () estimates and corrects harmonic distortions of the mains current via the current transformer (). The power transferred to a heated object as a function of the frequency is stored in a memory of the control unit (), so that the heated object is identifiable by its frequency-power characteristic. The frequency spectrum of the transferred power related to a harmonic distortion in the line (L) is stored in the memory () if the distortion exceeds a predetermined limit. The harmonic distortions are corrected by the control unit () if a heated object with the frequency-power characteristic related to the harmonic distortion is detected.
